Water Tested Following Herbicide Application On Chautauqua Lake

DEC-permitted 2018 herbicide treatments targeting the invasive/non-native Eurasian Water Milfoil and Curly Leaf Pondweed in Chautauqua Lake were completed on Monday, June 11.

A total of 81 acres was treated in five areas along the shoreline at Sunset/Warner Bay and Bemus Bay in the town of Ellery, the shoreline of the town of Busti and shorelines of Bly Bay and Sunrise Cove in the town of North Harmony. Swimming, fishing, livestock watering and animal consumption water use restrictions ended Tuesday, June 12.

Chautauqua Lake potable and domestic water use restrictions ended Tuesday after water sampling and subsequent testing showed herbicide residuals below the thresholds. Irrigation restrictions have ended in most areas of the lake, but remain for the Busti/Lakewood area of Chautauqua Lake and the Chadakoin River, Conewango and Cassadaga Creeks until sampling and testing indicate they can be removed. Warning signs at all lake access points except in Busti/Lakewood will now be removed.

Detailed information on treatment areas and water use restrictions and contact information can be found on the towns of Ellery, North Harmony and Busti websites.
